'. fication.

This invention relates to coke oven wall construction and more particularly to a coke oven of'the Semet-Solvay type.

As heretofln'c constructed the walls of these ovens have presented the disadvantage that they have been liable to collapse especially in their upper portions due chiefly to the fact that the prior constructions have been such that the inner tiers of bricks. and particularly those immediately beneath the cap bricks, have not been provided with any means for positively holding them in place. It is therefore one of the primary objects of the present invention to improve the wall construction of such an oven by providing for a locking connection or union between the uppermostbricks ot the inner tiers of the two walls of the oven and the cap bricks. so that the bricks of the inner tiers will not be liable to collapse.

Another object of the invention is to provide in such a wall construction, a novelform of fine brick.

In the drawings:

Figure 2 is a top plan view of one of the flue bricks:

Figure 3 is a view in elevation of one end of the flue bricks:

Figure 4 is a. similar view of the opposite end (if the brick;

Figure 5 is a perspective view of one of the bricks which go to make up the inner tier of each wall:

Figure 6 is a top plan view of the brick shown in Figure 5;

Figure 7 is a view similar to Figure 5,

The general arrangement and construction of'the oven walls is best illustrated in Figure 1 of the drawings and in this figure the numeral 1 indicates in general the two side walls of the oven, the numeral 2 the cap bricks of the walls, and the numeral 3 the arch bricks which span the space between the cap bricks and which constitute the top of the oven. i

Each of the side walls 1 0f the oven is of hollow construction as usual so as to provide the combustion spaces 4, and each wall comprises an outer tier of bricks indicated in general by the numeral 5 and an inner tier indicated in general b the numeral 6. Figure 10 of the drawings illustrates in perspective one of the bricks of the outer tier, this brick beingindicated in general by the numeral 7- and having a. flat or plane end 8. and provided in its op sitezfaces at its 0pposite lateral ed 5 with rabljets 9 providing tongues 10 adspting the bricks to be assembled with meetlng lateral edges of adjacent bricks interlocklng iii a manner which will be readily understood. Also the other end of each of the bricks 7 is rabbeted as at 11 to provide a, projecting tongue 12. Figure 5 of the drawing illustrates one of the bricks of the inner tier 6, this brick bein indicated in general by the numeral 13 and having a square or plane lower end 14 and provided in one lateral edge with a longitudinally extending dove-tail groove 15 and.

at its opposite lateral edge with an outstanding dove-tail rib or tongue 16. The upper end of this brick is rabbeted as at 17 thus providing an ii standing tongue 18,

and the groove 15 an the tongue 16 each extends for substantially one-half its respective widthinto the ton us 18. Of course, in assembling these bric s the tongues 16 of the bricks will fit into the groove 15 inthe mating edges of adjacent bricks so that as in the case of the bricks 7, the bricks 13 are locked together as they are built up to form the wall. In placin the bricks 7 and 13 in position, they are p need on end and. while the ends 8 and 14 of the bricks 7 and 13 are referred to above as their lower endb, these ends in fact become the upper ends in someof the courses of the tiers 5 and 6. In order that this may be better understood as also the purpose of the tongues 12 and 18 and rabbets 11 and 17, I will now describe the construction of the flue bricks and other bricks which are employed in the same relation as the flue bricks. Figures 2, 3, 4 and 8' of the drawings illustrate clearly the cough struction of one of the fluebricks, this brie? being indicated in of each brick is formed upon its upper and under sides with ribs 21 and 22. The ribs 21 and 22 extend at the opposite sides of the opening 20 and their opposin faces constitute extensions of the walls 0 this opening, the rib 21 being located parallel to that edge of the brick 19 which is to be the outer edge when the brick is in place within the wall (if the oven, and the rib 22 being located rallel to the edge of the brick which is to g: the inner edge when the brick is in place. One end of the brick 19 is indicated by the numeral 23 and the ends of the ribs 21 and 22 terminate, at this end of the brick, substantially in transverse alignment with the adjacent or correspondin end wall of the opening 20, their said an s being free from connection with each other. At their other ends, however, the ribs 21 and 22 are connected by a portion 24 which is extended, as indicated by the numeral 25, to the extreme corresponding end of the body of the brick both at the upper and under faces thereof.

The flue bricks 19 are interposed between the course of the bricks 7 and 13 com rising the tiers 5 and 6, the rabbets 11 an and 22 of the flue bricks and the said bricks 7 and 13 being disposed in relatively in- Werted positions in adjacent courses of the tiers so that in the lowermost course in each wall 1 shown in Figure 1 of the drawings, the uared lower ends 8 and 14 of the bricks 7 an 13 are lowermost and the rabbets 11 and 17 fit the ribs 21 and 22 upon the under sides of the flue bricks which are disposed u on their upper ends, nd in the next course above, the said bricks and 13 are inverted with relation to the bricks of the lower course so that their rabbets 11 and 17 then fit the ribs 21 and, 22 upon the upper sides vide bosses eneral by the numera 1' 19 and being provided substantially ceng trally with a flue opening 20. The body,"

ends in its under face as at 33 to I 17 of' the said bricks 7 and 13 fitting the ribs 21 of the flue bricks. In addition to the flue bricks 19 there are employed other bricks indicated in general by the numeral 26 and fore closed from end to end, being formed,

however, thicker at their central portions than at their marginal portions so as to pro- 27 upon their upper and under faces and thus form shoulders 'ainst which the edge portions of the square ends 8 and 14 of the bricks 7 and 13 may engage. In building up the walls, the bricks 19 and,26 in each course are alternately arranged, and where the ends 23 'of the bricks 19 occur, bricks indicated by the ranged transversely with relation thereto so as to span the space between the ribs 21 and 22 and the bricks 7 and 13 and thus form the re nired flues for the combustion products.

, ach tier 5 and 6 of each wall ina comprise, of course, any desired num er of courses but the arrangement is always such that the u permost bricks 7 and 13 will be provide at their upper ends with tongues which are indicated respectively specifically by the numerals 29 and 30, these tongues being fitted into grooves 31 and 32 formed in numeital 28 are ara the under sides of the cap bricks 2. In

this manner-a lock is rovided betwben the upper ends of the bricks 7 and 13 comprising the uppermost courses of the tiers, and the respective cap bricks 2 and thus I pro vide against collapse of this portion of the walls, which is the portion first to give way in the ordinary oven wall construction.

The arch brick 3 is rabbeted at its 0p osite fit the ad'acent ugeper corners of the cap bricks 2.

t will understood by those skilled in the art that b the use of each one of the flue bricks 19, Iain enabled to avoid the employment of six or more separate bricks which are at the present time made use of in forming the flue passages;

It is preferable that the blocks 26 shown in Figure 11 ofthe drawings be formed in their opposite ends and opposite faces with rabbets 34 so that wherever two of these blocks meet end to end in the construction of the oven wall, a lap joint will be formed.

Havingi thus described the invention, what is claims as new is:

1. In coke oven wall construction, spaced inner and outer tiers of bricks arranged in courses, and flue bricks disposed between the courses and each provided with anopenin and at opposite sides of the o ening wit ribs for engagement with the. a uttin ends of the first mentioned bricks, the sai ends of the first mentioned bricks being rabbeted to receive the ribs.

2. A flue brick for a coke oven wall coning therethrough, t
